    15,971 = 1874

    Two posts above lists 15,744 as 1873 so we can assume that 15,744 is likley from the very end of '73 and that serial # 15,971 is from early '74. It also shows they were making Petzvals at a fairly good clip at this point.

    Re: Hermagis Serial numbers Need your help with a database

    Taking delivery of serial no. 7242, which was originally a Convertible Petzval, I note a distinct variation from the numbers and signature styles already listed here. They are below. They were both on the achromat (2 numbers) and the thick concave (1 number).

    While checking the other earlier serial numbered Hermagis I find mine is the lowest number. There are 8xxx, 9xxx, 10xxx etc. It looks to me like Hermagis decided to start engraving numbers and decided to start at what they considered to accumulated numbers made to that date (or at a number that customers could accept as being realistic!). I see no connection with dates, but perhaps it relates to the single lens going into the Petzval or an internal stockbook of parts. The numbers are:

    209,67. and
    14015

    By the way, this is a pre-WHS model and the text is written "upside down" compared with other versions of this lens and the signs of the radial drive attachment have been completely removed when a later WHS was made in the sleeve.

    I think the odd third number in Gandolfi first list could be using the same system, especialy if it is an early one with no serial number or low number.

    Re: Hermagis Serial numbers Need your help with a database

    As I have something of a fetish/obsession about serial numbers and dates, I thought I might take up this thread again and see whether it is possible to make a reliable table.

    The booklet from Pont et Princelle (2009) says that earliest serial number (engraved on brass) they know of is 3,670. Whether the earlier lenses without serial numbers represent just Hermagis or Hermagis + Wallet et Hermagis + Derogy et Hermagis, is an open question.

    P et P give the following rough table.


    +/- 8000 +/- 1860
    12000. 1870
    20000. 1890
    35000. 1900
    50000. 1910
    65000. 1920
    100000. 1925
    130000. 1926
    150000. 1928
    200000. 1932
    220000. 1934

    We can easily improve on this with data we already have!

    The reason I have awoken this thread is that I have just bought this CdeV Hermagis Petzval.


    http://www.ebay.co.uk/itm/2225252426...%3AMEBIDX%3AIT

    This is, apparently, without a serial number (on the sleeve, anyway!) and has an undescribed (as far as I can find out) front washer aperture insert.

    Steven, If it helps my #1 is 73982 which puts in in the 1921-22 range. I'll have to check my #2.

    Re: Hermagis Serial numbers Need your help with a database

    This is the first attempt at a table. It is nice that there is no contradictory data!

    XXXX no brass serial number, "12 cent" on rear convex/concave. no. 7 plain Petzval. Blackened paper behind rack.
    YYYY no brass serial number. Many numbers. no. 9 plain Petzval. Blackened paper behind rack.
    ZZZZ no brass serial number, lens edges not seen- missing rear cell. size no.6?. blackened paper behind rack

    3670 first number noted by P et P. not confirmed! The photograph shows this is a modified sleeve. The pinion has been moved to the other side of the sleeve and the WHS cut-out has been made where the pinion was mounted. It appears the sleeve was originally as XXXX, YYYY etc.

    Start of Serial numbers. 6285 ( and 7010) are engraved with the granted Patent, which was in July 1856. So 6285 cannot be before 1856. I venture to suggest that serial number engraving was begun at the same time this was granted.

    ----------------------------------------------------------------------------------------------------

    6285 many digits, but no date - barrel engravings. Convertible
    6872 digits but no date. barrel engraving Convertible#
    7004. no date but signature on lens - sleeve engraving. Convertible
    7010. P et P illustration p.8 - barrel engraving. Convertible.
    7242 many digits, but no obvious date. Convertible.
    8154. only hermagis on achromat. address and 1859 on rear. no.3 convertible
    8268. catawiki auction huge ordinary Petzval with bayonnet rear pair
    8745. D'Agostini
    8077 many digits, no obvious date

    9305 P et P
    9804. D'Agostini

    16457. 1876
    16723. 1876
    16784. 1876
    16944. 1876
    17025. P et P

    18635 1880 These two lenses suggest that there may have been a stock of lenses with
    18702. 1883. their completion date added, but serial numbers were added later.
    19411. 1884. Large plain Petzval

    24312. (1)891 These are the final digits in a long series. Matches with production levels - of the late 80's early 90's.






    The remaining 6 are from the 20th century.

    It is obvious that the P et P table is very wrong about a serial number of 12,000 in 1870
